Collection of Space Rocks on Loan
Visit us this summer and see the impressive display of meteorites in the Edward L. Clark Museum of Missouri Geology. A space rock smaller than approximately one yard across will likely burn up completely during passage through Earth’s atmosphere. This is what we see as meteors (shooting stars) and fireballs. Larger space rocks up to approximately 10 yards across have a good chance of landing intact or in pieces on the Earth as meteorites.
Self-guided tours of the museum are available to the public weekdays from 8 a.m. to 5 p.m. Admission is free! Closed on Holidays, we are located at 111 Fairgrounds Road, Rolla. Admission is free of charge. Check our website for more information.

Celebrate Earth Science Week With Us!
Stop by our Edward L. Clark Museum of Missouri Geology Wednesday, Oct. 17 and celebrate National Fossil Day with us. In addition to seeing our impressive display of fossils, visitors to the museum will receive a small Crinoid stem fossil (the official state fossil) to add to their personal collections.
The third annual National Fossil Day is being held during Earth Science Week. Gov. Jay Nixon declared the week of Oct. 14 through Oct. 20 as Earth Science Week 2012 to bring awareness to the fact that earth sciences are fundamental to the health, safety and welfare of all Missourians.
“Discovering Careers in the Earth Sciences” was selected by the American Geosciences Institute as the theme of Earth Science Week 2012 to boost awareness about the geosciences and the many exciting career and job opportunities in the field. Through careers in geology, geophysics, oceanography, hydrology, paleontology, earth science education and many other fields, they enhance our understanding of Earth processes and improve the quality of human life. Organized in 1998 by American Geosciences Institute, the Department of Natural Resources’ Division of Geology and Land Survey and other sponsors participate as a service to the public and the geoscience community. The program is supported by the U.S. Geological Survey, National Aeronautics and Space Administration, the National Park Service and other major geoscience groups.

Celebrate Earth Science Week With Us!
Neil Elfrink, one of our geologists will give a 30-minute presentation about the mining in Phelps County Tuesday, Oct. 16. Neil’s talk will begin at 7 p.m. at the Holloway House, 10th and Holloway, Rolla, Mo. There will be time for questions. This event is sponsored by the Phelps County Genealogical Society. The public is welcome to attend and admission is free.
This special presentation is being held during Earth Science Week, which is October 14-20 and special exhibits will be on display at our Edward L. Clark Museum of Missouri Geology during Earth Science Week. For example, Wednesday, Oct. 17, is National Fossil Day when visitors to the museum will receive a small Crinoid stem fossil (the official state fossil) to add to their personal collections.
A highlight of this year’s activities will include the first-ever Geologic Map Day. Geologic Map Day will be held Friday, Oct. 19 to promote awareness of the study, uses, importance of geologic mapping for education, science, business, and a variety of public policy concerns. Special exhibits and maps will be on display in the museum.
Located at 111 Fairgrounds Road, in Rolla, the museum is open weekdays from 8 a.m. to 5 p.m. Admission is always free.
See clearly the importance of Missouri sandstone
Look through the window of your house or your car, or maybe even your water glass and you are probably looking at sand. Actually, you are looking through a product made from a very pure form of silica sand (silicon dioxide, or SiO2), and there is a chance it originated as a part of Missouri geology. Sand has been mined for glass manufacture in Missouri since the Pittsburgh Plate Glass Company began operating in Jefferson County in the 1870s. This sand is mined from a formation called the St. Peter Sandstone which is highly pure quartz sandstone. Recently, producers have been putting nearly half a million tons of this Missouri based industrial mineral into the market each year for that purpose. Take the opportunity throughout the day to realize how often you see or use a glass product. You may be looking right through some Missouri geology. Learn more about this important resource.
Visit our geology exhibit at the Missouri State Fair today through Sunday, Aug. 19, 2012
Be sure to stop by the historic Womans Building to see our impressive display of rocks, minerals and fossils. The Womans Building is 101 years old this year. Our exhibits are considerably older. The Womans Building is #13. It is located near the Pepsi Grandstand. Grandstand. See a map of the Fairgrounds.
If you are in Rolla, stop by our Edward L. Clark Museum of Missouri Geology and see a shark spine fossil that our staff discovered and retrieved from its ancient hiding place in 2006 near Branson. In addition to this ancient fossil, we have corals, bryozoans, crinoids, trilobites, rocks, minerals and exhibits related to Missouri geology on display. The museum is open for self-guided tours weekdays from 8 a.m. to 5 p.m. We are located at 111 Fairgrounds Road in Rolla, Missouri. Admission is free.
Did you know Missouri is the number one producer of lime in the United States?
Missouri industries produce nearly 2.5 million tons of lime each year at a value of approximately $237 million. This equates to more than 18 percent of U.S. production. Due to the large domestic production, lime is one of a few of more than 60 mineral commodities produced in the U. S. that is not necessary to import. The U.S. actually exports more than 160,000 tons each year.
There are literally thousands of uses for lime that impact our daily lives. Uses range from the manufacture of paper, plastics, rubber, glass, steel and other metals, to treating and cleaning water, wastewater, and air emission in the process of using fossil fuels. It serves a myriad uses in the food industry including the reduction of carbon dioxide produced by stored fruits and vegetables, thereby lengthening their storage time. Used in the production of milk and milk products such as butter, lime is also found in baby food, stomach antacid and tooth paste. Interestingly enough, all quality tortillas and corn chips are treated with lime. So the next time you have a really good tortilla, remember which lime really gave it that special flavor.
Minerals help make the moment!
Did you know that at one time saltpeter mined from several Missouri caves was used to manufacturer fireworks? It is true and the compound barium nitrate (from the mineral barite) is also used in fireworks. Without minerals such as these, the colorful display fireworks afford us each Independence Day would not be possible.
Each color in a fireworks display is produced by a specific mineral compound. For example, deep reds are made with strontium, blues are a product of copper, yellows come from sodium and bright greens require barium. More colors can be created by mixing compounds and some minerals are used for special effects. For example, a loud flash/bang is created by using fine aluminum powder.
The role of minerals in fireworks is just one example of society’s reliance on minerals for the manufacture of everything from automobiles to glass. Learn about minerals in Missouri.
We invite you to visit our Ed Clark Museum of Missouri Geology. to see numerous minerals, rocks and fossils on display. We are open for self-guided tours weekdays from 8 a.m. to 5 p.m. We are located at 111 Fairgrounds Road in Rolla, Missouri. Admission is free.
As always, be safe this Fourth of July and adhere to local regulations that are in place for setting off fireworks. –Joe
What is this mineral and why is it so popular?
Since early in the 20th century fuller’s earth has been mined in significant quantities from southeast Missouri. Currently more than 400,000 tons of this clay material is being mined in Missouri each year with an annual value of $30 million. Because this clay mineral is mostly made up of hydrous aluminum silicate it possesses an excellent ability to absorb oil based substances. Centuries ago, wool cloth makers known as “fullers” used this mineral to remove lanolin and other oils from woolen materials. More recently it is used in the treatment of pulmonary fibrosis, and to absorb contamination from military personnel involved in chemical and biological warfare. This mineral’s ability to absorb oils is also why it is used in the cosmetics industry as facial clay treatments to treat acne. However, you may be familiar with one of today’s more common uses of fuller’s earth — cat litter. Read more at this U. S. Geological Survey website about fuller’s earth and other clay production. Also, see our Mineral Resources fact sheet for addtional information about mineral resources in Missouri. –Jerry
